There was a series of number ranges that mapped onto other ranges. The simple approach was filling dictionaries, which worked well for the example data. In the actual data, there ranges were much much larger (in the 100,000,000’s), which made the dictionaries prohibitively large.
If you don’t know the meaning of a word, you can literally Google “{The word you don’t know} definition.” Google.com is a really handy and easily-accessed dictionary.

I mean, that literally failed just yesterday.
Also I’m not sure where in today’s problem you would even use a dictionary
Hey, I haven’t been doing Advent this year. What was day 5’s problem and why did dicts fail?

If each number was 8 bytes wide, it would require, if I didn’t mess up my math, 18 GB to fully represent all seeds/numbers as an array.

I can’t tell if this is a joke or a troll, buy we’re talking about a Dictionary, which is a common data structure in computer science.
